Effects of clustering instructions and category size on free recall of nonretarded and retarded children. 1978

G J Reichhart, and J G Borkowski

The effects of category size and instructions to cluster on the free-recall learning of 112 nonretarded and retarded children were assessed. Simultaneously presented lists of 12 pictures composed of 2, 3, or 6 categories were shown for three study-test trials. Instructions to cluster significantly increased recall and cluster scores on a new list for both nonretarded and retarded children. The category-size effect was weak, although it was related to the magnitude of the correlations between organization and recall scores.

D008297	Male		Males
D008568	Memory	Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
D008607	Intellectual Disability	Subnormal intellectual functioning which originates during the developmental period. This has multiple potential etiologies, including genetic defects and perinatal insults. Intelligence quotient (IQ) scores are commonly used to determine whether an individual has an intellectual disability. IQ scores between 70 and 79 are in the borderline range. Scores below 67 are in the disabled range.
